2. before, carrying out " linkage " operation, it is necessary to ensure that the steel wire rope of main and auxiliaries is in tensioning state, Otherwise subsidiary engine steel wire rope there will be to tighten up suddenly and shakes.

3., before starting winch, it is necessary to ensure that the steel wire rope on main and auxiliaries reel does not has disorder cable phenomenon.

4., in operation, local console and one people of centralized operation platform needs, monitor winch fortune Row state, presses " emergent stopping " button when there is situation.

5., when cable laying, it is desirable to have people monitors the length releasing steel wire rope, it is not possible to release too much, otherwise The phenomenon of disorder cable easily occurs, occurs that disorder cable must stop at once, again that cable arranging is neat.

6., must confirm before each tractive that tractive stop position photoswitch is normal, rope is long and detect proximity switch Normally.

7., ensureing that switch board surrounding air is dried, system exceedes first quarter moon and does not works, and need to power on one in this work Operate again after hour.

(9), operation and maintenance

1., ensure not want overload operation when using, will operate in strict accordance with operating procedure and points for attention.

2., periodically carrying out maintaining, running check wiring nose, should be timely when dust is the thickest with or without loosening Cleaning, otherwise, may make insulation reduce and cause short circuit or " blowing out ".

3., change element time, component parameters should be checked and approved, such as pressure, electric current, size etc., note during wiring Polarity.

4., make regular check on sensor and connect the most solid and reliable.

5. system earth, is made regular check on the most reliable.

6., make regular check on band-type brake open instruction proximity switch the most normal.

7., each safety guard of system to be ensured working properly, must not arbitrarily remove.

8., regular purging system switch board, the drainage screen of frequency conversion tank is the most once cleared up, it is ensured that system Stable operation.
